Liquid Analytical Accessories
Accessories that enhance liquid analysis performance and uptime: flow cells, holders, fittings, and cleaning assemblies. Designed to protect sensors, maintain correct flow/immersion, and enable quick maintenance for consistent data quality.
Frequently Asked Questions
What is the function of an immersion fitting in liquid analytics?
An immersion fitting is designed to safely position analytical sensors, such as pH or dissolved oxygen probes, at a specific depth within open tanks, basins, or channels. It protects the sensor cable and provides a secure, accessible mounting method that facilitates easy retrieval for calibration or maintenance.
Why are retractable sensor assemblies necessary for continuous processes?
Retractable assemblies allow sensors to be safely withdrawn from pressurized process lines or tanks without requiring a system shutdown or process interruption. This is critical in continuous manufacturing where sensors require frequent cleaning, calibration, or replacement without halting production.
How do automated cleaning systems extend the life of analytical sensors?
Automated cleaning systems use timed cycles of water, chemical solvents, or compressed air to remove process buildup and biological growth from the sensor's measuring surface. By keeping the sensor clean, these systems ensure measurement accuracy, reduce manual maintenance intervals, and significantly extend the sensor's operational life.
What role do flow-through chambers play in sample analysis?
Flow-through chambers are used in bypass lines to provide a controlled, low-flow environment for analytical sensors, away from the turbulence and high pressure of the main process pipe. They ensure stable, representative measurements and often incorporate ports for easy introduction of calibration buffers.
Why are specialized cables required for pH and ORP sensors?
pH and ORP sensors generate extremely high-impedance, low-voltage signals that are highly susceptible to electromagnetic interference and moisture degradation. Specialized shielded coaxial cables are required to transmit these delicate signals reliably to the transmitter, ensuring accurate and stable process readings.
